Q. Match the organism with its properties in a food chain:
Organism Role in the food chain Nutrition Trophic level
$1.$ Grass $i.$ Secondary Consumer $a.$ Herbivores $w.$ Third
$2.$ Grasshopper undefined Tertiary Consumer undefined Primary Carnivores $x.$ Fourth
$3.$ Rodents $iii.$ Producer $c.$ Secondary Carnivores undefined First
$4.$ Cats $iv.$ Primary Consumer $d.$ Transducers undefined Second

Solution:

Grass is at the First Trophic level as it is a producer. It can convert sunlight to chemical energy hence it is a transducer. Grasshoppers (herbivores) eat grass and hence are primary consumer at second trophic level. Rodents eat Grasshoppers and thus are secondary consumers and also primary carnivores at third level. Cats eat Rodents and are Tertiary consumer and secondary carnivores at fourth trophic level.
